APPARATUS FOB CONTRULLING THE DELUERY 03F LIQEUJIDS.

i .eeiaaa To all whom t may concern:

lle it known that l, ALFRED ARTHUR Quien, a subject of the King of Great Britain, residing at Clifton Hill, in the State of Victoria, Commonwealth of Australia, have invented certain new and useful Iniprovenients in Apparatus -for Controlling the Delivery otI Liquids, ot which the tollowing is a specification.

This invention relates to an improved apparatus for controlling the delivery ot liquids and refers more particularly to an apparatus for the control ot the delivery of milk to the public from cans or vessels containing the same.

The obj ectot this invention is to provide means by which a control is maintained over the liquid to prevent its being tampered with or adulterated. lt accomplish this object by providing means whereby the liquid is retained in the vessel by which it is conveyed from the source of supply aud only withdrawn therefrom through a mechanically controlled device into another closed delivery can or vessel in such manner that it cannot be tampered with in transit.

The means for extracting the liquid troni vessels containing the same into the delivery cans or vessels consists ot a tap device comv prising two separate elements, one of which is adapted to be attached to the tirstenained vessel, and the other to the delivery can or vessel, the arrangement being` such that these elements are capable or' operation only when connected together.

lin order that this invention may be better understood l will now proceed to describe the same with reference to the accompanying drawings in which my invention is shown as applied to the delivery el" milk and in which Figures l and 2 are vertical sectional views ot the tap or valve element which is adapted to be connected to the vessel to be emptied; Fig. 3 is a section of the socket element which is attached to the receiving vessel; and Figs. 4land 5 are vertical sectional views showing the two elements engaging; each other.

Referring' to Fig. 3, a delivery bucket or vessel is provided having a removable cover 26. This cover QGis adapted to iit upon the bucket 25 with a rubber or other washer Q8 so that a hermetic joint may be etlected. and suitable tastenings are provided so that said cover may be locked in Specification of Letters Patent.

position and sealed it necessary. lllithin the cover QG is mounted a socket Q0. having a series oit holes and adapted to lit within a cylinder 8l; also having a series ol holes 32 (shown in dotted iii-.ies in said l `io;. corresponding1 with the holes d0. il. screw is provided engaging a slot le by which the movementot the cylinder :il is limited along its longitudinal axis. lllitlr in the cylinder 31 is a screw #le having a longitudinal slot 3G at the top and rotatably secured to the bottoni ot the said (':ylinder 3l, a spring being provided bearino; against the bottom or the socket Q5). "lhiis by ope 1atingl the screw 35 as hereinafter described the cylinder 3l is drawn upward until the holes 32 are coincident with the holes 80, allowing),` ol the flow of mh..

For the purpose ot operating the screw S5 only by the connection ot the bucket 2' with the supply can or vessel (not shown), lt provide a special construction of tap illustrated in Figs. l and 2. This tap consists of a casing 41:0 having' an inlet iil which is adapted to be connected to the outlet pipe. (not shown), leading lroin the supply7 can or vessel by a hose or flexible pipe. lllithiu this casing' L t0 is a hollow plug t2 having a hole 43 adapted to coincide with the inlet ill. Upon the plug e2 is a handle Ltl by which the same may be I`fi'iven a half-turn. Upon the top of the plug' ifQ is a hollow casingt5 containing: a spring' 4:6 operating' as hereinafter described. '.lhis casingl is capable oit being' secured to the casing l0 by a rod t engaging a lug t8 which .is sealed or otherwise looked thereto. it the bottom the hollow plug' 4:2 projects into another hollow plug.)I 4t!) and the two are locked together by a thumb screw by which their correct relative position may be determined. rlllhe hollow plug i9 is adapted to lit within the socket .29 in the cover Q6 of the bucket 25, and is formed with a series of holes 5l adapted to coincide with the holes 30 therein. The hollow plug;` t9 is also torined with a spiral A.eroove F9. adapted to engage a pin or projection 37 in the said socket 99. Extending longitudinally throughoutthe tap is a rod 53 having an operating; handle 54 at its upper end and at its lower end a fiat key 55. Surrounding' this rod 53 is a sleeve havinfr a cap 5'? at its upper end against which the spring' t6 bears, and at its lower end an enlargement 58 which is adapted to engage the bottom edge ot the hollow plug 42, thus forming a valve. fit the bottom of this enlargement. 58 is an internally screw-threaded socket. 59 adapted to engage the screw 35.

The delivery pipe leading from the supply vessel is connected to the inlet 41 of the tap 40, and the plug 49 is then inserted into the socket 29 so that the spiral groove 52 engages the pin or projection 87. A haltturn movement of the handle 44 brings the hole 43 coincident with the inlet 41 and allows the milk to flow into the interior of the hollow plug 42. At the same time the pin or projection 37 in the socket 29 engaging' the spiral groove 52 draws the said hollow plug 49 down into the socket and locks it in position so that itl can not be withdrawn from the socket 29 without the handle 44 being returned into its former position, thereby cutting oli the supply of milk through the inlet 41. The plug 49 being` connected to the socket 29, the handle 54 is turned, whereupon the lat key 55 on the rod 53 is caused to engage the slot 36 of the screw 35. The thread upon the screw 35 engages the internally threaded recess 59 at the bottom of the sleeve 56. This sleeve is then drawn downward, compressing the spring 46, and at the same time the enlargement 5S is drawn out of engagement with the bottom edge of the hollow plug 42. The action of this screw 35 draws the cylinder 31 upward, compressing the spring 8S and bringing the holes 32 coincident with the holes 3G. In this way the holes 80 in the socket 29, the holes 32 in the cylinder 31, and the holes 51 in the hollow plug 49 are all made coincident, and the milk or other liquid is thus allowed to iiow from the inlet pipe 41 into the interior of the plug 42 and therefrom through the aforementioned series of holes into the interior of the bucket 25 and it will be seen that the milk is only in this way allowed to flow from the supply can or vessel into the receiving bucket 25, and immediately he same is disconnected the iiow of milk is cut oit. It therefore cannot be tampered with in transit.

Having thus fully described my invention, l claim:

1. In an apparatus for controlling the delivery of liquids from a supply vessel into a receiving` vessel; a tap device for connecting said vessels with each other comprising a casing adapted for connection with the 55 supply vessel and having an intake opening; a socket attached to the cover of the receiving vessel, and provided with a pin;

a cup connected to said casing and adapted to project into said socket, said cup being 60 formed with a. spiral groove for engagement by said pin; a. hollow plug valve arranged within said casing; and a handle for operating said plug, said cup and socket being provided with co-acting means for pe-rmitting communication between the cup and the interior of the receiving vessel.

2. ln an apparatus for controlling the delivery of liquids from a supply vessel into a receiving vessel; ar tap device for connecting said vessels with each other comprising a 4casing adapted for connection with the supply vessel and having an intake opening;

a socket attached to the cover of the receiving vessel; a. slot-ted screw projecting into Said socket; a cut-oit device to which said screw is connected; a cup connected to said casing and adapted to project into said socket, said cup and socket being provided with coacting means for permitting coinmunication between the cup and the interior of the receiving vessel; a valve arranged within said cup for ceac-tion with said screw; and a rod extending longitudinally through said tap device and provided at one end with an operating handle and at its other end with a key adapted for reception in the slot in said screw. i

ln testimony whereof l have hereunto Set my hand in presence of two subscribing witnesses.
